Three different things under one heading, and none replaces another:
- Manufacturer batteries: Nikon EN-EL15c, Canon LP-E6NH, Sony NP-FZ100 at 2280mAh, plus the VB30 for the Godox V1PRO flash. Each body takes one specific reference, so the exact part number outranks every other consideration.
- Vertical grips: Canon BG-R20, BG-R20EP and BG-E16, Nikon MB-N11, Sony VG-C4EM. They extend runtime, improve the hold and put a shutter release and dials where your hand falls in portrait orientation — how portrait, fashion and wedding work is actually shot.
- Backup power: the Jupio charger plate for NB-12L and the Newell Asvala Mini station, 24000mAh with a 220V outlet and 18W USB-C PD, for long days away from a socket.
